Abstract
The purpose is to compare minimum 10-year patient-reported outcome (PRO) scores and survivorship following open treatment of FAIS to a propensity score-matched group of arthroscopically treated patients.
Methods
Data was prospectively collected on patients followed for minimum 10 years after open dislocation of the hip to treat FAIS. The following PROs were collected preoperatively and long-term: modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and Visual Analog Scale (VAS) score for pain. Clinical outcomes were assessed using the patient acceptable symptomatic state (PASS), minimum clinically important difference (MCID), and maximum outcome improvement satisfaction threshold (MOI), as well as survivorship. Patients were compared 1:3 through propensity score-matching to an arthroscopically treated cohort.
Results
Nine eligible patients met inclusion criteria, with an average follow-up of 117.5 ± 22.2 (range, 103.0– 132.0), matched to 28 patients on the arthroscopic group. Both groups presented significant improvement from preoperative scores to latest follow-up (P>0.05). The average deltas
were also comparable, though trending toward significance [mHHS: 16.5 ± 15.0 vs 25.2 ± 19.4 (P = 0.177), NAHS: 13.9 ± 16.7 vs 30.3 ± 18.9 (P = 0.080), HOS-SSS: 20.2 ± 26.1 vs 36.1 ± 23.6 for the control group (P = 0.096). Patient satisfaction between groups was similar [(7.80 ± 2.4/10 vs 8.46 ± 1.4 (P = 0.363)]. Patients in both groups demonstrated comparable rates of achieving MCID, PASS, and MOI (P > 0.05). Although not significant, survivorship average time was longer for open procedure (45.4 vs 35.1), but rate was higher on arthroscopy [(82.1 vs 66.7%) p=0.3]. Patient satisfaction was 7.7 ± 2.1 vs 8.5 ± 1.4 (0.363).
Conclusions
Hip arthroscopy and open surgical dislocation prove to be equivalently effective treatment options for FAIS, demonstrating significant improvement from preoperative to long-term outcomes and high rates of post-operative survivorship.
